The following is a list of vessels. Place them in the order that blood would go through entering the systemic circulation. 1. Le
Alexus [3.1K]

Answer:

E. 3, 6, 7, 4, 5, 8, 1, 2

Explanation:

Systemic circulation is the circulatory pathway which is involved in the transport of the oxygenated blood to the body when pumped by the heart through arteries, capillaries and then back to the heart.

In the given question, the order of vessels in the systemic circulation has been asked which begins with the entry of the deoxygenated blood to the heart.

1. The deoxygenated blood enters the blood from vena cava to the right ventricle.

2. From the right ventricle, the blood enters the right atrium which pumps the de-oxygenated blood to the lungs through an artery called the pulmonary artery.

3. In the lungs, the blood becomes oxygen rich and is returned to the left atrium through the pulmonary vein.

4. The blood then enters the left atrium which is then pumped to the body through the main artery called the aorta.

This completes the systemic circulation and thus, Option-E is correct.

Answer:

Explanation:

Australopithecina or Hominina is a subtribe in the tribe Hominini. The members of the subtribe are generally Australopithecus (cladistically including the genera Homo, Paranthropus,[2] and Kenyanthropus), and it typically includes the earlier Ardipithecus, Orrorin, Sahelanthropus, and Graecopithecus. All these related species are now sometimes collectively termed australopithecines or homininians.[3][4] They are the extinct, close relatives of humans and, with the extant genus Homo, comprise the human clade. Members of the human clade, i.e. the Hominini after the split from the chimpanzees, are now called Hominina[5] (see Hominidae; terms "hominids" and hominins).

While none of the groups normally directly assigned to this group survived, the australopithecines do not appear to be literally extinct (in the sense of having no living descendants) as the genera Kenyanthropus, Paranthropus and Homo probably emerged as sister of a late Australopithecus species such as A. africanus and/or A. sediba.

The terms australopithecine, et al., come from a former classification as members of a distinct subfamily, the Australopithecinae.[6] Members of Australopithecus are sometimes referred to as the "gracile australopithecines", while Paranthropus are called the "robust australopithecines".[7][8]

The australopithecines occurred in the Plio-Pleistocene era and were bipedal, and they were dentally similar to humans, but with a brain size not much larger than that of modern apes, with lesser encephalization than in the genus Homo.[9] Humans (genus Homo) may have descended from australopithecine ancestors and the genera Ardipithecus, Orrorin, Sahelanthropus, and Graecopithecus are the possible ancestors of the australopithecines.[8]
