Answer:
High concentrations of vasoconstrictor substances will increase the peripheral resistance.
Explanation:
Vasoconstriction substances cause blood vessels to narrow their lumen. The more narrow lumens, harder it is for the blood to go through that vessel. The reason for this is because the resistance increased, meaning that the friction between the blood and the vessels' walls is higher.
When we talk about peripheral resistance, it means the sum of all individual resistance of the body blood vessels (all arteries, all capillaries, all veins).

A Tarsorrhaphy is the partial or complete suturing together of the upper and lower eyelids.
<h3>What is the partial or complete suturing together of the upper and lower eyelids?</h3>
- An easy and safe operation called tarsorrhaphy joins some or all of the upper and lower eyelids to partially or completely hide the eye.
- A Tarsorrhaphy is the partial or complete suturing together of the upper and lower eyelids.
- By fostering a more favourable environment for corneal healing, tarsorrhaphies are very helpful in treating nonhealing epithelium abnormalities and other corneal surface diseases.
- Tarsorrhaphies can be total or partial, permanent or temporary, and can be further broken down into tarsorrhaphies with or without sutures for a short period of time, tarsorrhaphies with temporary sutures, tarsorrhaphies with permanent sutures, and more extensive tarsorrhaphies that involve mobilizing skin or tarsal plate flaps.
- A temporary tarsorrhaphy is appropriate when improvement over a few weeks is predicted because it enhances corneal repair during a brief time of illness or exposure.

Answer:
The answer is A true
Explanation:
A myocardial infarction that produces an alteration of the ventricular filling will be associated with a decrease in cardiac output; Typical in myocardial injuries where muscle dysfunction leads to a decrease in the amount of blood to be pumped or the capacity to fill it.
