Digestive by Tia

The digestive system is a long, twisting tube that starts at the mouth and goes through the oesophagus, stomach, small intestine, large intestine and ends at the anus. The digestive system breaks down food into simple nutrients such as carbohydrates,fats and proteins

3 most important features of the digestive system:

wisdomap143 — 2024-02-24 15:28:11 UTC

The digestive system has three main functions relating to food:

1) digestion of food

2) absorption of nutrients from food

3) elimination of solid food waste

Circulatory

wisdomap143 — 2024-02-24 15:33:27 UTC

Circulatory is the system that contains the heart and the blood vessels and moves blood throughout the body. This system helps tissues get enough oxygen and nutrients, and it helps them get rid of waste products.

Important features of the circulatory system:

wisdomap143 — 2024-02-24 15:39:44 UTC

The circulatory system consists of four major components:

1) heart

2)arteries

3)veins

4) blood

Respiratory

wisdomap143 — 2024-02-24 15:44:54 UTC

The respiratory system is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary history.

The most important feature of the respiratory system:

wisdomap143 — 2024-02-24 15:57:03 UTC

The main organ of the respiratory system is the lungs. Other respiratory organs include the nose, the trachea and the breathing muscles (the diaphragm and the intercostal muscles).

Endocrine

wisdomap143 — 2024-02-24 16:02:09 UTC

The endocrine system is a messenger system in the organism comprising feedback loops of hormones that are released by internal glands directly into the circulatory system and that target and regulate distant organs.

The most important feature of the endocrine system:

wisdomap143 — 2024-02-24 16:15:38 UTC

The endocrine system, made up of all the body's different hormones does the following:

1) regulates all biological processes in the body from conception through adulthood and into old age.

2) development of the brain and nervous system.

3) function of the reproductive system, as well as the metabolism and blood sugar

Musculoskeletal

wisdomap143 — 2024-02-24 16:20:33 UTC

Bones, muscles and joints make up the musculoskeletal system, along with cartilage, tendons, ligaments and connective tissue.

wisdomap143 — 2024-02-24 16:20:56 UTC

The most important feature of the musculoskeletal system:

wisdomap143 — 2024-02-24 16:27:20 UTC

Skeletal muscle tissue composed of bundles of muscle fibers called myofibers which contain several myofibrils. Each myofiber represents a muscle cell with its basic cellular unit, the sarcomere. Bundles of myofibers form fascicles, and bundles of fascicles form muscle tissue.

Nervous

wisdomap143 — 2024-02-24 16:32:42 UTC

The nervous system has two main parts: The central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts pf the body.

The most important feature of the nervous system:

wisdomap143 — 2024-02-24 16:39:27 UTC

The human nervous system is made up of three basic parts:

1) the central nervous system

2) the peripheral nervous system

3) autonomic nervous system

Without a doubt, it is the most complex part of the human body / "The Nervous System which is known to be the masterpiece of nature.

Immune

wisdomap143 — 2024-02-24 16:46:39 UTC

The immune system is a complex network of organs, cells and proteins that defends the body against infection, whilst protecting the body's own cells. The immune system keeps a record of every germ (microbe) it has ever defeated so it can recognise and destroy the microbe quickly if it enters the body again.

3 most important feature of the immune system:

wisdomap143 — 2024-02-24 16:54:11 UTC

3 major features of the immune system:

1) to fight disease-causing germs (pathogens) like bacteria, viruses, parasites or fungi, and to remove them from the body.

2) to recognise and neutralize harmful substances from the environment.

3) to fight disease-causing changes in the body, such as cancer cells.

Reproductive

wisdomap143 — 2024-02-24 16:59:37 UTC

The reproductive system of an organism, also known as the genital system, is the biological system made u[ of all the anatomical organs involved in sexual reproduction. Many non-living substances such as fluids, hormones, and pheromones are also important accessories to the reproductive system.

wisdomap143 — 2024-02-24 16:59:50 UTC

3 of the most important features of the reproductive system:

wisdomap143 — 2024-02-24 17:05:07 UTC

The 3 main features of reproduction is:

1) to produce egg and sperm cells.

2) to transport and sustain the cells.

3) to nurture the developing fetus and produce hormones.
