The right atrium receives the de-oxygenated blood from the body. From the right atrium blood passes to the right ventricle.
The right ventricle propels this de-oxygenated blood to the lungs though pulmonary artery, for oxygenation. The deoxygenated blood loses carbon-di-oxide and gains oxygen in the lungs. This process is called gaseous exchange.
After the gaseous exchange, blood becomes oxygenated. This oxygenated blood comes to left atrium of the heart through pulmonary veins.
From the left atrium blood comes to the left ventricle. Left ventricle sends this oxygenated blood through aorta and arteries to all organs of the body.
<h3><u>Answer;</u></h3>
Morphology
The taxon species may be defined by <em><u>reproductive isolation and morphology </u></em>
<h3><u>Explanation;</u></h3>
- <em><u>A taxon is a group of one or more populations of an organism. </u></em>
- <em><u>Morphology is the form or the appearance of a particular organism, </u></em>while <u><em>reproductive isolation is the separation of organisms by some type of barrier.</em></u>
- <em><u>Reproductive isolation is a type of mechanisms that prevent two or more organisms or populations from exchanging genes through reproduction. </u></em>This occurs when two organisms or species are separated for too long such that they can no longer reproduce with each other due to different adaptation and changes in the environment.
- <u><em>Morphology and reproduction isolation may be defining characteristics of taxon of species.</em></u>
Bone Marrow is tissue in the hollow centers of our bones, it has stem cells which produce our blood cells. It also produces red blood cells that give oxygen to the whole body. Hope this helped : )
