State the differences in compositionof blood between the aorta and main vein
Ad libitum [116K]

Answer:

The placenta is a unique vascular organ that receives blood supplies from both the maternal and the fetal systems and thus has two separate circulatory systems for blood: (1) the maternal-placental (uteroplacental) blood circulation, and (2) the fetal-placental (fetoplacental) blood circulation. The uteroplacental circulation starts with the maternal blood flow into the intervillous space through decidual spiral arteries. Exchange of oxygen and nutrients take place as the maternal blood flows around terminal villi in the intervillous space. The in-flowing maternal arterial blood pushes deoxygenated blood into the endometrial and then uterine veins back to the maternal circulation. The fetal-placental circulation allows the umbilical arteries

Correctly label the anatomical features of the muscle filament.
irina [24]

The labeled anatomical features of the muscle filament are attached as an image.

Muscle filament or Myofilaments are the two protein filaments of myofibrils in muscle cells. The two proteins are myosin and actin and are the contractile proteins involved in muscle contraction.

  • It has two filaments, a thick one made up mostly of myosin, and a thin one composed mostly of actin
  • Actin is a filament made up of protein that contributes to the contractile property of muscle. It is found in two forms, G-actin (monomeric globular actin) and F-actin (polymeric fibrous actin)
  • Tropomyosins are contractile proteins that regulate contraction in both muscle and non-muscle cells with help of myosin and actin filaments. It is present in animal cells.
  • A troponin complex is a group of three proteins, troponin T, troponin I, and troponin C, subunits located on the thin filament of the contractile apparatus.

Thus, the correct labeled anatomical features of the muscle filament is attached as an image.
