♥cardiovascular system♥
♥This components of the cardiovasculary system includes the hear, blood, and the blood vessels.
The one that pumps the blood through out our body is the heart. it has four chambers; two at the upper and smaller than the two lower parts. The two upper is namely at left and right atrium, while the two lower are named as left or right ventricle. The hear is surrounded by a serous membrane called as pericardium. Heart has its movement to pump the blood, it is called as cardiac cycle.
The next is Blood. Blood has very important functions. Blood transports oxgens, helps to regulate a variety of levels in the body to maintain homeostasis, also blood protect us from invasion and infection by pathogens and toxins. Blood's major contents are plasma. There are RBC also as red blood cells or erythrocytes, WBC also as white blood cells, or leukocytes and Thrombocytes or platelets.
Lastly is the blood vessels. Arteries carries blood away from the heart, while veins carry blood to heart. Capillary is a blood vessels that has thin walls so that it can allow for exchanges of waste products.
In this chapter, there has been a lot of knowledge that I have learned. Although this chapter was long, it is still interesting to know about this especially the heart and how it works. :)

♥Special Senses♥
Here in special senses, i hate learned to differentiate the general and special senses. I knew that parts and layers of the eye. Each structure has a distinct characteristic which makes the organ more wonderful than we ever know during on our elementary years. Also the external and internal parts of the ear was elaborated well! The reporter also discussed about the processes involved with the senses of taste, smell, and touch.
Senses plays a very important role in our everyday lives. So it is good to know about them =)
