What is the function of the venticles?
The ventricles are the main pumping chambers of the circulatory system. They pump blood to the body carring oxygen and to the lungs to pick up oxygen.
Which class of drugs increases the forcefulness of the pumping of the heart but not the oxygen?
One class of drugs that increases the forcefulness of the heart's pumping without affecting oxygen consumption is positive inotropic agents, such as digoxin. These drugs improve contractility, leading to increased force of contraction and cardiac output. However, they do not change the oxygen demand of the heart.
Why does the blood flow from the different the parts of the body?
The oxygen within the blood is depleted and needs to be returned to the lungs to be re-oxygenated.
When a person exercises the cells of the body need more oxygen This achieved by what system increasing the amount of oxygen that is supplied to the blood?
When we are participating in any kind of physical activities our heart rate increases to 50-75% means more blood is pumping through our entire system. Because of these actions breath will increase and we inhale more oxygen.
Describe the path of the blood through the body?
You breath in oxygen, oxygen goes to the lungs. The oxygen is carried from the lungs to the heart. The blood cells are filled with oxygen, then pumped through your body. If you feel on your neck below your jaw, you should feel your pulse. This is an artery pumping blood to your brain. Then, the used blood is pumped back to your heart to receive more oxygen and then is pumped back to somewhere in your body.
How is oxygen depleted blood carried to the lungs?
This is through the Pulmonary Circulation.
Where does veins carry oxygen depleted blood to?
Veins carry oxygen depleted blood to the heart.
Why are aerobic muscles red?
Because there is blood pumping through them to deliver glucose and oxygen.
Depleted of oxygen?
Hypoxia is the term used for low, or depleted, oxygen levels. It occurs naturally at high altitudes or in the deeper regions of the sea.
What is the main function of the respiratory system in a animal. supportingb bones-taiking oxygen into the body-digesting food-pumping blood through the body?
Taking oxygen into the body
Differentiate a vein from an artery?
Arteries always carry blood to an organ/area, conversely veins always carry blood away. Interestingly Arteries can be thought to carry blood rich in oxygen, whereas veins carry oxygen depleted blood. When I was younger I remembered this as (Artery = Air), it's crude but it worked. There are 2 major vessels however that are the exception to this rule. The Pulmonary Artery, which carries oxygen depleted blood from the heart to the lungs. and the Pulmonary Vein which carries oxygen rich blood back to the heart. Happy Pumping
How can a body of water can be depleted of its oxygen?
Water can be depleted of it's oxygen by a number of different ways. Short of putting the water in a vacuum and "sucking" the dissolved oxygen out, oxygen-breathing organisms such as fish take oxygen from the water through respiration, for example. It is unlikely a large body of water to become completely deoxygenated due to the presence of photosynthetic aquatic organisms (plants) and the fact that oxygen is also dissolved in the water at the water's surface.
Where the blood takes the oxygen?
Answer: Oxygen-depleted blood from the body enters the right atrium through two veins, the superior vena cava and the inferior vena cava. The blood then passes to the right ventricle. The right ventricle pumps the deoxygenated blood to the lungs, through the pulmonary artery. After the blood loses carbon dioxide and picks up oxygen in the lungs, it flows through pulmonary veins to the left atrium. From the left atrium the newly oxygenated blood enters the left ventricle. The left ventricle is the main pumping chamber, sending blood through the aorta to all of the body except the lungs.
What allotrope of this element is being depleted from earth's stratosphere?
oxygen
What occurs if energy reserve in a muscle are depleted after heavy exercise?
an oxygen debt
Why do you puff so much after you run?
The blood is racing around our body so fast. This is due to the heart pumping and pumping. For the heart to pump, we need to breath, this is performed by air being sucked in and blown out (DUH!). We breath because we need to get oxygen to our brains. The oxygen is transported through our blood cells.
Why does blood have to pass through the heart twice to get around the body once?
because the blood gets depleted of its oxygen content once it reaches the heart and it needs to be oxygenated when it goes to the different parts of the body. as you may notice, the heart is divided into four chambers. the right side deals with the unoxygenated blood while the left side deals with the oxygenated blood. since the heart has no capacity to supply oxygen depleted blood with oxygen, it has to pass first to the lungs before it is pumped to the different parts of the body.
