Answer:
The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body's tissues through the aorta.

<em>Protein-energy malnutrition has two severe forms: and kwashiorkor (a lack of protein) and marasmus (a lack of protein and calories).

An insect or other animal that transmits a disease-causing organism from one host to another is a vector.
<h3>What is a vector?</h3>
A vector is widely known as a carrier of a disease-causing agent or pathogenic microorganisms.
A vector carries disease-causing agents from an infected host to a healthy host, hence, causing a risk of infection in the healthy host.
Examples of vectors are as follows;
- Mosquitoes
- Aphids
- Tse tse fly
- White fly
- Ticks
Therefore, the insect or other animal that transmits a disease-causing organism from one host to another is a vector.
