The first answer is given. Nose- The organ through which air enters and is filtered. 10 Thuman suction system

Pharynx – The pharynx is a tube made of skeletal muscle and lined with mucosa that is continuous with that of the nasal cavities.

Larynx – The larynx is a cartilaginous structure below the laryngopharynx that connects the pharynx to the trachea and helps regulate the volume of air entering and exiting the lungs. The structure of the larynx consists of several pieces of cartilage.

Human Heart: Anatomy, Function & Facts

Trachea – The trachea (trachea) extends from the larynx to the lungs. The trachea consists of 16 to 20 stacked, C-shaped pieces of hyaline cartilage that are connected by dense connective tissue.

Bronchial tree – The trachea branches into the right and left primary bronchi at the level of the carina. These bronchi are also lined by pseudostratified ciliated columnar epithelium containing mucus-producing goblet cells.

Respiratory zone – Unlike the conductive zone, the respiratory zone includes structures that are directly involved in gas exchange. The respiratory zone begins where the terminal bronchioles join a respiratory bronchiole, the smallest type of bronchiole, which then leads to an alveolar duct, opening into a group of alveoli.

Alveoli – An alveolar duct is a tube composed of smooth muscle and connective tissue that opens into a group of alveoli. An alveolus is one of many small, grape-like sacs that are attached to the alveolar ducts.

Bone tissue, or bone tissue, is a hard, dense connective tissue that forms most of the adult skeleton, the body’s internal support structure. In areas of the skeleton where whole bones move against each other (for example, joints like the shoulder or between the bones of the spine), cartilage, a semi-rigid form of connective tissue, provides flexibility and smooth surfaces for movement. In addition, ligaments composed of dense connective tissue surround these joints, binding skeletal elements together (a ligament is the dense connective tissue that connects bones to other bones). Together, they perform the following functions:

Some functions of the skeletal system are easier to see than others. When you move, you can feel how your bones support you, facilitate your movement and protect your body’s soft organs. Just as the steel beams of a building provide a scaffolding to support its weight, the bones and cartilage of your skeletal system make up the scaffolding that supports the rest of your body. Without the skeletal system, you would be a soft mass of organs, muscles and skin. Bones facilitate movement by serving as attachment points for your muscles. Bones also protect internal organs from injury by covering or surrounding them. For example, the ribs protect your lungs and heart, the bones of the vertebral column (backbone) protect your spinal cord, and the bones of the cranium (cranium) protect your brain (see Figure 6.1.1).

At the metabolic level, bone tissue performs several critical functions. First of all, bone tissue acts as a reservoir for a number of minerals important for the functioning of the body, especially calcium and phosphorus. These minerals, incorporated into bone tissue, can be released back into the bloodstream to maintain levels necessary to support physiological processes. Calcium ions, for example, are essential for muscle contractions and are involved in the transmission of nerve impulses.

Bones also serve as a place for fat storage and blood cell production. The unique connective tissue that fills the inside of most bones is called bone marrow. There are two types of bone marrow: yellow bone marrow and red bone marrow. The yellow bone marrow contains adipose tissue, and the triglycerides stored in the adipocytes of this tissue can be released to serve as an energy source for other body tissues. The red bone marrow is where the production of blood cells (called hematopoiesis, hemato- = “blood”, -poiesis = “to make”) takes place. Red blood cells, white blood cells, and platelets are all produced in the red bone marrow. As we age, the distribution of red and yellow bone marrow changes, as seen in the figure (Figure 6.1.2).

Figure 6.1.2 – Bone Marrow: Bones contain varying amounts of yellow and/or red bone marrow. Yellow bone marrow stores fat, and red bone marrow is responsible for producing blood cells (hematopoiesis).

An orthopedist is a doctor who specializes in diagnosing and treating disorders and injuries related to the musculoskeletal system. Some orthopedic problems can be treated with drugs, exercises, braces and other devices, but others are best treated with surgery (Figure 6.1.3).

While the origin of the word “orthopedics” (ortho- = “straight”; paed- = “child”) literally means “to straighten the child,” orthopedists can have patients ranging from pediatric to geriatric. In recent years, orthopedic surgeons have even performed prenatal surgery to correct spina bifida, a birth defect in which the neural canal in the fetus’s spine does not close completely during embryological development.

Human Circulatory System

Orthopedists usually treat bone and joint injuries, but they also treat other bone conditions, including curvature of the spine. Lateral curvatures (scoliosis) can be severe enough to slide under the shoulder blade (scapula), forcing it up like a hump. The curvatures of the spine can also be excessive dorsoventrally (kyphosis) causing a hump of the back and chest compression. These curves often occur in preteens as a result of poor posture, abnormal growth, or undetermined causes. For the most part, they are easily treated by orthopedists. As people age, accumulated spinal injuries and diseases such as osteoporosis can also lead to curvatures of the spine, hence the stooping you sometimes see in older people.

Some orthopedists subspecialize in sports medicine, which addresses both simple injuries, such as a sprained ankle, and complex injuries, such as a torn rotator cuff in the shoulder. Treatment can range from exercise to surgery.

The major functions of the skeletal system are to support the body, facilitate movement, protect internal organs, store minerals and fats, and form blood cells.

In a multicellular organism, an organ is a collection of tissues united into a structural unit to perform a common function.

In the hierarchy of life, an organ is between a tissue and an organ system. Tissues are made up of cells of the same type to act together in a function. Tissues of different types combine to form an organ that has a specific function. The intestinal wall, for example, is made up of epithelial tissue and smooth muscle tissue.

Two or more organs that work together to perform a specific body function form an organ system, also called a biological system or body system.

Digestion: Anatomy, Physiology, And Chemistry

The tissues of an organ can be broadly classified as parchyme, functional tissue, and stroma, structural tissue with supporting, connective, or auxiliary functions. For example, the gland tissue that produces hormones is the parchyme, while the stroma includes the nerves that innervate the parchyme, the blood vessels that oxygenate and nourish it, and transport its metabolic wastes, and the connective tissues that provide a suitable place for it to
