Where do the branches of the bronchial tree ultimately end? 2. list the steps of the pulmonary circuit of the cardiovascular sys
Aneli [31]
1. The branches of the bronchial tree ultimately ends at the alveoli.
Bronchial tree consist of bronchi, bronchioles, and alveoli. Bronchi are formed as the lower part of the trachea divides into two tubes. Bronchioles are smaller tube divisions of the bronchi. It walls contain smooth muscle and no cartilage. Alveoli are tiny ends of the alveolar ducts, which functions as the site for gaseous exchange. 

2. Blood flows from the left atrium; mitral (bicuspid valves), the left ventricle, aortic valve, aorta, veins and heart, right side of the heart, superior and inferior vena cavae, right atrium, tricuspid valve, right ventricle, pulmonary valve, pulmonary trunk, pulmonary artery, lungs, pulmonary veins, then back to the heart...

3. Arteries and the veins differ in structures and they way they functions; Arteries carry oxygenated blood away from the heart to the body (except pulmonary artery) while veins carry deoxygenated blood back from the body to the heart (except pulmonary veins). A structural differences includes; the veins contain valves while arteries lack. Arteries have narrow lumen while veins have wide lumen. Lastly, blood carried by veins has higher pressure compared to blood carried in vessels.

4. The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and the bronchioles. Blood moves in and out of the lungs throgh the pulmonary arteries and veins that connect to the heart.

5. The cartilage rings of the trachea
They are strong but flexible tissues which support the trachea or the windpipe while still allowing it to move and flex during breathing. Additionally these cartilage rings are C-shaped to provide room for the esophagus, which lies along the back side of the trachea.

6. Functions of the larynx includes;
To protect the airway from choking on material in the throat
to regulate the flow of air into our lungs
The production of sounds used for speech 
Larynx is part of the respiratory system and is located between the pharynx and the trachea. Humans use larynx to breathe, talk and swallow. 

7. Structures that make up the pathway of air through the respiratory system starting with the external nares; We start with; External nares, nasal cavity, internal nares, nasopharynx, laryngopharynx,oropharynx, larynx, trachea, primary bronchus, secondary bronchus, tertiary bronchus, bronchiole, terminal bronchiole, respiratory bronchiole, alveolar duct, alveolar sac and alveolus.

Can someone send me their table for 3.13 meaning of mitosis assignment plz
Firlakuza [10]

Mitosis, a procedure of cell duplication, or multiplication, amid which one cell offers ascend to two hereditarily indistinguishable girl cells. Carefully connected, the term mitosis is utilized to depict the duplication and dissemination of chromosomes, the structures that convey the hereditary data.

A concise treatment of mitosis pursues. For a full treatment, see development: In cells; cell: Mitosis and cytokinesis.

Preceding the beginning of mitosis, the chromosomes have imitated and the proteins that will frame the mitotic axle have been incorporated. Mitosis starts at prophase with the thickening and curling of the chromosomes. The nucleolus, an adjusted structure, shrivels and vanishes. The finish of prophase is set apart by the start of the association of a gathering of strands to frame a shaft and the breaking down of the atomic layer.

The chromosomes, every one of which is a twofold structure comprising of copy chromatids, line up along the midline of the cell at metaphase. In anaphase every chromatid pair isolates into two indistinguishable chromosomes that are destroyed to inverse closures of the cell by the shaft strands. Amid telophase, the chromosomes start to decondense, the axle separates, and the atomic films and nucleoli re-structure. The cytoplasm of the mother cell partitions to frame two girl cells, each containing indistinguishable number and sort of chromosomes from the mother cell. The stage, or stage, after the consummation of mitosis is called interphase.

P.S. You're a mean person. You ought to pursue different people groups bearing and don't simply answers something for focuses. Fortunately, I revealed you and your answers got delted and afterward erased the 50 points that you escaped your focuses. Try not to do that or else no one's going to like you. Bye....

Also the image below show that I didn't copy. It says it's 100% original and i got it from paperrater.com
