What happens After the heart pumps oxygen rich blood to the aorta then the oxygen rich blood enters cells where does it go next?

After the heart pumps oxygen-rich blood into the aorta, the blood travels through a network of arteries and arterioles, eventually reaching the capillaries where oxygen is delivered to the cells. Once the oxygen is utilized by the cells for metabolic processes, carbon dioxide and other waste products are produced. The deoxygenated blood then collects these wastes and returns to the heart through venules and veins, ultimately entering the right atrium to be pumped to the lungs for reoxygenation.

What parts of the respiratory system and circulatory system work together?

the diaphragm is one of them im not sure what the other is

the diaphragm is one of them im not sure what the other is

Name 5 human body systems?

There are many different body systems for example, "Muscular, skeletal, reproductive, respiratory, and integumentary".

The systems of the human body are the Digestive, Respiratory, Circulatory, Muscular, Skeletal, Reproductive, Nervous, and Excretory.

What are four different causes of circulatory failure?

Cardiogenic shock- results from any type of heart failure.

Hypovolemic shock- results from the loss of blood volume in the blood vessels "low blood".

Neurogenic shock- results from widespread dilation of blood vessels caused by an imbalance in autonomic stimulation of smooth muscles in vessel walls.

Anaphylactic- results from an acute allergic reactioncalled anaphylaxis.

During exercise why do you breathe faster?

We breath faster because we're tired of running and if we hyperventilate then we don't have to run anymorebecause all organs of body than required more energy,as a great work is being done i-e exercise.Its well known that oxygen is utilized in the break down of body food,glucose.so more work,more energy,more oxygen,more breathing

What is the purpose of cardiovascular system?

To:

a) Carry oxygen from the lungs to your cells.

b) Carry chemical "messengers" called Hormones throughout your body.

c) Carry nutrients to the cells

d) Carry wastes away from your cells

e) Spread heat throughout the body.

What would expect to find being transported in your blood?

Too numerous to list them all. Here are a few examples:

oxygen bacteria viruses proteins ions amino acids plasma waste products from cells hormones respiratory gas PH arterial blood gas

and many more

Where do the digestive system and the circulatory system connect?

Mainly through hepatic portal vein which connects liver and small intestine

What are any other names for the circulatory system?

The circulatory system is also known as the cardio-vascular system.

What are some harmfuul things that can hurt the circulatory system?

Healthy habits that help to keep your circulatory system in good shape are: eating well-balanced meals--that include plenty of fresh fruits and vegetables, getting daily exercise, keeping your stress down, interacting with those you love and care about, holding on to a positive attitude, getting plenty of sleep and enjoying your life.

Two basic types of circulatory systems that have evolved over time?

open and closed circulatory systems.
open system: the blood leaves the discrete vessels and bathes at least some non-vascular tissues directly. (crustaceans, mollusks, arthropods, etc.)


closed system: there is always at least a thin vessel wall separating the blood from the other tissues. (mammals,birds, etc.)

Is it true that as ventilation increases and more carbon dioxide is removed from the blood the hydrogen ion concentration of the blood decreases?

Yes it is true. That's what doctors call sometimes respiratory alkalosis (when the pH of the blood goes higher up than...). What happens its very simple and cool. As you hyperventilate you win a lot of oxygen molecules but you also loose a lot of carbon dioxide molecules (in the physiological exchange of CO2 for O2 between the alveoli and the pulmonary capillaries). This decrease in CO2 in the blood decreases the amount of CO2 molecules dissociating into HCO3- and H+ when it interacts with the water molecules. This explains the decrease in H+ molecules and the increasing of the PH

What does the circulatory systems do?

Allows for oxygen to be transported to the cells in your body, and transport the body's waste products out of the body.

How blood is circulated inside the foetus?

opposite as in a born person deoxygenated blood is in the arteries and oxygenated blood in the veins
