Blood Vessels

Blood vessels are the tubular structures that carry blood throughout the body. There are three main types of blood vessels: arteries, veins, and capillaries.

Arteries

Arteries are blood vessels that carry blood away from the heart. They have thick, muscular walls that allow them to withstand the high pressure of blood being pumped from the heart. Arteries also have a layer of elastic tissue that helps them expand and contract as blood is pumped through them.

Veins

Veins are blood vessels that carry blood back to the heart. They have thinner walls than arteries and have valves that help prevent the backflow of blood. Veins also have a lower pressure compared to arteries.

Capillaries

Capillaries are tiny, thin-walled blood vessels that connect arteries and veins. They are the site of exchange of nutrients, oxygen, and waste products between the blood and the surrounding tissues. Capillaries have a large surface area and are the primary site of gas exchange in the body.

Circulatory System

The blood vessels, along with the heart, form the circulatory system. This system is responsible for transporting blood, nutrients, gases, and waste products throughout the body. The circulatory system is essential for maintaining homeostasis and ensuring that all cells receive the necessary nutrients and oxygen.

Nature of Science

The Practice of Science - A: Scientific inquiry is a multifaceted activity; The processes of science include the formulation of scientifically investigable questions, construction of investigations into those questions, the collection of appropriate data, the evaluation of the meaning of those data, and the communication of this evaluation. B: The processes of science frequently do not correspond to the traditional portrayal of ''the scientific method.'' C: Scientific argumentation is a necessary part of scientific inquiry and plays an important role in the generation and validation of scientific knowledge. D: Scientific knowledge is based on observation and inference; it is important to recognize that these are very different things. Not only does science require creativity in its methods and processes, but also in its questions and explanations.

Define a problem based on a specific body of knowledge, for example: biology, chemistry, physics, and earth/space science, and do the following:

Use tools to gather, analyze, and interpret data (this includes the use of measurement in metric and other systems, and also the generation and interpretation of graphical representations of data, including data tables and graphs)
