This is a question on the circulatory system. I don't understand how the pathway that the blood goes through in the heart makes it oxygenated. Could someone pleas explain to me what each part does and how when it goes to the lungs it gets oxygenated?
Answer:
deoxygenated blood is pumped back to the heart with the superior vena cava and inferior vena cava. Blood is then in the right atrium then it is pushed to the right ventricle in the heart. it is the pumped through the pulmonary artery to the lungs(the pulmonary artery is the only artery that carries deoxygenated blood). In the lungs blood is pumped to the cappilleries in the bronchus where oxygen in the air is passed through to the blood with heamoglobin and thus now the blood is oxygenated. The blood is the pumped brought back to the heart with the pulmonary vein(the pulmonary vein is the only vein to carry oxygenated blood).It flows into the left atrium where it is then pushed down into the left ventricle and is then pumped up through the aorta to the whole body.

the diagram shows two cells found in human blood.
a. the actual diagram of
red blood cell is 0.007mm ( 7 um) in diameter.
Calculate the magnification of the diagram. show your working.
side note: I measured it in a ruler and it's 2.3 cm = 23 mm (drawn to scale)
a)
Actual diameter = 0.007 mm
Diameter of scaled diagram = 2.3 cm = 23 mm
Formula to use:
Magnification = scaled dimension/actual dimension
Magnification = 23/0.007
Magnification = 3285.714... → x3286
b)
Red blood cells (RBCs), otherwise known as erythrocytes, don't have nuclei and organelles such as mitochondria, are smaller than WBCs and have a biconcave disc shape ideal for purpose
c)
i.
RBCs transport oxygen inhaled into the lungs around the body to all tissues and organs
ii.
RBCs are void of organelles so they are maximally packed with haemoglobin to bind and transport oxygen;
The biconcave disc shape is ideal for flowing through the blood vessels, particularly the capillaries, optimising them for transporting oxygen;
The small size also helps in being able to circulate the vasculature effectively and successfully

Which organism carries out autotrophic nutrition
Answer:
Autotrophs is the answer
Example : plants
Plants and some bacteria (e.g., cyanobacteria) carry out autotrophic nutrition, synthesizing their own organic molecules using light or inorganic substances.
Organisms that carry out autotrophic nutrition are capable of producing their own organic compounds and energy sources using inorganic substances. One example of an organism that performs autotrophic nutrition is plants. Plants possess specialized structures called chloroplasts that contain chlorophyll, a pigment responsible for capturing sunlight energy.
Through the process of photosynthesis, plants convert carbon dioxide and water into glucose, a form of stored energy. This energy is then used by the plant for growth, development, and other metabolic processes. Additionally, some bacteria and protists are also capable of autotrophic nutrition. These organisms utilize different mechanisms such as chemosynthesis or photosynthesis to synthesize their own organic compounds and derive energy from non-organic sources, such as inorganic chemicals or light, respectively.

where are unmyelinated nerve fibers surrounded by schwann cells?
Schwann cells without myelination are seen in the peripheral nervous system (PNS).
Myelinating Schwann cells and non-myelinating Schwann cells are the two different kinds of Schwann cells. One kind of neuroglial cell is the Schwann cell. Nerves are helped and supported by neuroglial cells. Nerve impulses can be sent at speeds of about 270 miles per hour thanks to the ability of Schwann cells to speed up the process.The myelinating Schwann cell coils around nerve axons with large diameters. The myelinating Schwann cell creates the neurilemma, a lipid base membrane, as it loops itself around the nerve fiber. The myelin sheath develops from the neurilemma.However, unlike a hotdog bun that encircles a hotdog, the non-myelinating Schwann cell does not form myelin; instead, it permits thin nerve fibers to rest along, within, and on top of the non-myelinating Schwann cell. Non-myelinated nerves often have slower nerve transmission.Learn more about the Schwann cells with the help of the given link:
