The blood is collected in heparinized capillary tubes to prevent clotting. Heparin is a blood thinner and this anticoagulant is produced naturally by mast cells and basophils. But heparin can not dissolve or break the preformed clots.
A certain minivan has a maximum carrying capacity of 1,200 pounds. The luggage weighs 150 pounds
Answer:
Oxygen molecules in the tissues of the lung diffuse into the blood because the concentration of oxygen in the lung's tissues is more than the concentration of oxygen in the blood.
Explanation:
Diffusion is the movement of molecules from the region of higher concentration of the molecule to the region of lower concentration of the same molecule. Molecules in diffusion move <em>downward the concentration</em> <em>gradient</em> created by difference in concentration between two regions until an <em>equilibrium (equal concentration in the two regions)</em> is established.
Oxygen molecules diffuse into the tissues of the lung when an organism breathes-in during the process of breathing. The molecules in the now oxygen-rich tissues eventually start diffusing into the blood in the lung because the blood passing through the lung is always de-oxygenated or has lower oxygen concentration compared to the tissues of the lung.
Oxygenated blood moves into the heart, pumps round the body by the heart, gets depleted of oxygen and eventually find its way back to the lung where the process is repeated.
Diffusion of oxygen from the tissues of the lung into the blood will keep happening as long as oxygen keeps getting dissolved into the lung's tissues and an equilibrium is yet to be established between the tissues and the blood.
Hi lovely,
Are you able to provide your answer choices?
Muscles which are responsible for the movement of the eyeball have fast fibers. Thus, the correct option is A.
<h3>What are fast muscle fibers?</h3>
Fast-twitch muscle fibers are the muscle fibers which provide bigger and more powerful forces, however for shorter durations and fatigue quickly. They are more anaerobic with less blood supply, and hence are sometimes also referred to as white fibers or type II fibers.
Fast-twitch muscle fibers are activated by the high intensity movements which are sustained in short bursts. Examples of movements include sprints, burpees, and quick lateral movements.
Therefore, the correct option is A.
