Answer: D) much slower
Explanation:
The circulatory system, made up of arteries and veins, is fundamental to maintaining life. Its function is the delivery of oxygen and nutrients to all cells, as well as the removal of carbon dioxide and waste products, the maintenance of physiological pH, and the mobility of the elements, proteins, and cells of the immune system. An artery is each of the vessels that carry blood with oxygen from the heart to the capillaries of the body. They arise from a ventricle and their walls are very strong and elastic to resist the pressure that the blood exerts when it is pumped out of the heart.
Capillaries are very small diameter, thin-walled blood vessels connect small arteries (arterioles) to veins, allowing nutrients and oxygen to pass through to tissues. The main function of the capillaries is the exchange of substances between the light of the capillaries and the cell interstice of the tissues.
When the blood reaches the capillary bed, the speed with which it circulates inside these vessels is very low. This is due to the fact that in a branching system of tubes, the speed decreases proportionally to the increase in the joint section of the branches. Thus, in the aorta, which has a small section, the speed is very high (400 mm/sec), it decreases at the level of the arteries and arterioles and at the capillary level it becomes minimal (0.1 mm/sec). <u>This fact, together with the thinness of the capillary wall, provides the necessary conditions of time and space for the exchange to take place in the most optimal way.</u>

Answer:
(1): CONNECTIVE
(2): PLASMA
(3): INJURY
(4): 55%
(5): RED BLOOD CELLS
(6): WHITE BLOOD CELLS
(7): THROMBOCYTES
(8): ERYTHROCYTES
(9): LEUKOCYTES
(10): PLATELETS
Explanation:
In terms of its tissue classification, blood is classified as a ____CONNECTIVE______tissue because it’s extracellular matrix determines its function. Blood is composed of living blood cells, called formed substances, suspended in a nonliving fluid matrix called ___PLASMA________. The "fibers" of blood only become visible during ______INJURY____________. When blood is centrifuged, the plasma is less dense and rises to the top. It makes up ___55%_____ of whole blood. The other 45% is comprised of 3 formed elements, scientifically they are called: ____RED BLOOD CELLS_______ (RBC), _____WHITE BLOOD CELLS____ (WBC) and ____THROMBOCYTES_____(platelets). The heavier blood cells become packed at the bottom. Most of the bottom is composed of _____ERYTHROCYTES___________. The "buffy coat" separates these two areas. It is composed of ____LEUKOCYTES______ and ___PLATELETS_______.
overall, the cell cycle is the copying and division of a cell. It consists of 4 main parts: G1, S, G2, and M
