Explanation:
The papillary muscles of both right and left ventricles began to contract shortly before the other ventricular muscles (systole) so that they can take up the slack on the chordae tendineae as the full force of ventricular contractions sends blood against the atrioventricular (AV) valve flaps.
They prevent the backward flow of blood to atria from ventricles. So if they contract after the ventricle systole they would not be able to perform their job.
Answer:i think At a chemical synapse, one neuron releases neurotransmitter molecules into a small space (the synaptic cleft) that is adjacent to another neuron. The neurotransmitters are contained within small sacs called synaptic vesicles, and are released into the synaptic cleft by exocytosis.
Explanation: i hope this answer your question....
The difference between primates and hominids: a primate refers to members of the ORDER Primate which includes monkeys, lemurs and apes. A hominid is a member of the FAMILY Hominidae (great apes) which includes gorillas, chimpanzees, orangutans, and us humans. A hominid is just a specific group of primate. Meaning, since the order primate composes of monkeys, lemurs and apes, the hominid is just a certain kind of primate belonging to the "ape" category, which differentiates it from other primates who belong to the "monkey" or "lemur" subtype.
I hope this helps.
