What oil will most likely lead to a blockage of blood flow in body

coconut oil

How does blood flow through the body?

blood (red blood cells) filled with wastes like carbon dioxide enters the inferior vena cava(lower body) or the superior vena cava (upper body) in the heart and goes to the right atrium and goes to the right right ventricle though the tricuspid valve. from there the blood goes to left and right lungs to drop off the carbon dioxide for the organism to exhale and picks up oxygen through the pulmonary valve and pulmonary artery and returns back to the heart through the pulmonary vein and into the left atrium. from there in goes to the left ventricle through the mitral valve. oxygen rich blood flows through the aortic valve to the aorta to go to the rest of the body. from there oxygen rich blood flows through arteries until it gets to a place like the big toe. capillaries connect arteries to veins. capillaries take the oxygen from the blood cells and puts carbon dioxide and other wastes in them. next, the blood goes to the veins back to the heart and goes through the inferior vena cava and the cycle start all over again until blood cells travel to the liver 120 days after they are made in large bones like the femur(thigh bone).

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
