reflex response

Answer 1

my answer is transport of oxygen

Answer 2

u are absolutely right.:D

Answer 3

Thnx

Answer 4

its because :
The circulatory system consists of the heart, blood and blood vessels.

The functions of the circulatory system are:
Transport gases, like oxygen from the lungs to cells around the body and carbon dioxide from the cells to the lungs.
Transport nutrients like glucose.
Transport wastes from cells to organs that play the role of eliminating them.
It contains cells that fight infections and defend against foreign bodies.
Maintains the pH levels and ionic concentration of fluids in the body.
Helps maintain the body temperature, this is especially important in warm blooded animals like humans.
to carry nutrients to and waste away from every cell in your body As the name suggests, the circulatory system is involved with circulating blood (or fluid connective tissue) throughout the body. I doing so, the following objectives are met:
Providing oxygen to all tissues in the body
Removing waste products
Gas exchange in the lungs
Supports the immune system cells
Maintains body temperature
The main function of the circulatory system is to get blood throught the body.
Your blood is pumped around by the heart which is the main function in your circulatory system. The heart sends blood through your blood vessels. The circulatory system consists of the heart, blood vessels, lymph, blood, and the lymphatic vessels and glands.

The Circulatory System is an organ system that allows blood and lymph to transport oxygen, carbon dioxide, nutrients, white blood cells, metabolites, hormones and many more to and from different tissues in the body helping to maintain homeostasis.

The Circulatory System is an organ system that allows blood and lymph to transport oxygen, carbon dioxide, nutrients, white blood cells, metabolites, hormones and many more to and from different tissues in the body helping to maintain homeostasis.
The Circulatory System is responsible for transporting materials throughout the entire body. It transports nutrients, water, and oxygen to your billions of body cells and carries away wastes such as carbon dioxide that body cells produce. It is an amazing highway that travels through your entire body connecting all your body cells. The main job is to keep blood flowing throughout the body, which helps you do all of your everyday functions, as your blood cells need oxygen, and the circulatory system makes blood flow from the heart to the lungs so the cells can get oxygen so the body can do everyday functions and work properly and correctly. transfer blood through all parts of the body
It circulates blood throughout the body to deliver oxygen, nutrients and other essential materials to cells, and to remove waste products.

The three main parts of the circulatory system are:
1. the heart
2. the blood
3. and the blood vessels heart and blood vessels
the prime function of the CVS(CardioVascular System) is to supply blood to the whole body & thru blood supply the body tissues with nutrients n oxygen tht r dissolved in the blood n similarly provide an outlet 4 waste cellular metabolites like carbon dioxide,ammonia etc... mostly the whole body and every I mean every part of the body.
To name a few
1) supplying oxygen to the body
2) supplying nutrients to the body
3) supplying the wastes to the excretory organs of the body for elimination
4) immunological
5) maintaining body temperature
6) supplying the drugs and medicine to the target organ
7) maintaining the internal body pressure
8) transporting hormones from source gland to the target body part
9) absorption of the digested food from the elimentary canal (not lipids & fats)
10) the level of various blood contents is of great significance in diagnosing any deviation of the body functioning from normal, eg. B.urea, B. sugar, etc.
Each alveolus is surrounded by capillaries. Capillaries are the smallest blood vessels in the cardiovascular system. Inside each lung, oxygen in the air moves through the walls of the alveoli and into the capillaries. In the capillaries, the oxygen binds to red blood cells, which are carried in the blood stream through the rest of the body. As the oxygen rich red blood cells move through the cardiovascular system, they release the oxygen to the body.
