The cardiovascular system is a component of the circulatory system (the other component being the lymphatic system) and consists of the heart, blood vessels and blood. Its 3 main functions include:
1. Transport of oxygen and nutrients toward and wastes away from cells of our body
2. Immunological protection of our body from foreign organisms and substances
3. Maintenance of homeostasis including the regulation of body temperature, blood pressure, electrolytes and water balance.
Because the cardiovascular system interacts with other organs of the body in a complex fashion, you cannot simply state that it has one main or overall function. Like most organ systems of the body it serves several vital roles which are necessary for the survival of the organism. However, in terms of IMPORTANCE, the function of transportation (of which oxygen if often cited as essential) would probably rank as paramount above the maintenance of homeostasis and immunologic protection.
Transport- Transportation of oxygen, nutrients and hormones to cells and removal of metabolic wastes such as carbon dioxide, heat and nitrogenous wastes.
Regulation- Of body tempreture, fluid pH and water content of cells
Protection- By white blood cells, antibodies and complement proteins that circulate in blood and defend again foreign microbes and toxins. Also white blood cells clot when body is injured.
There are two: the digestive system and the cardiovascular system.
1. Respiratory system 2. Cardiovascular system
The cardiovascular system is made up of the heart (which pumps blood) and the blood vessels (which transport blood throughout the body).
The respiratory system and the circulatory (cardiovascular) system.
I believe it's the cardiovascular system and the respiratory system.
The circulatory system, which includes the heart, blood vessels, and blood, is responsible for distributing oxygen and nutrients to all parts of the body. Oxygen and nutrients are carried in the blood and delivered to cells throughout the body.
The two organs responsible for bringing oxygen into the body are the lungs and the cardiovascular system. The lungs extract oxygen from inhaled air and transfer it to the bloodstream, while the cardiovascular system circulates the oxygenated blood throughout the body to deliver it to cells.
Bivalves have a two-part hinged shell that encloses their soft body. Their body functions include filter-feeding, where they draw in water to extract nutrients and oxygen, as well as locomotion using a foot to burrow or move along the seafloor. They also have a simple nervous system and sensory structures to detect changes in their environment.
The four major functions of the human body are: supplying the body with oxygen and removing carbon dioxide through respiration, providing structure and support through the skeletal system, facilitating movement through the muscular system, and coordinating bodily functions through the nervous system.
The nervous system and the endocrine system regulate and control the body's functions. The nervous system uses electrical signals to transmit information quickly, while the endocrine system uses hormones to regulate various processes more slowly. Together, they maintain homeostasis and coordinate the body's responses to internal and external stimuli.
The respiratory system removes carbon dioxide from the body by exhaling it from the lungs. The cardiovascular system also plays a role by transporting the carbon dioxide to the lungs where it can be exhaled.
1) Transport of oxygen into the body 2) Transport of carbon dioxide out of the body
