Journal 5

Encounter

My encounter with Histology occurred on Sabbath. My friends and I went to Capital Hill SDA and it was communion Sabbath there. We enjoyed it very much. Pastor Nelson spoke about the exodus from Egypt and the preparation the Israelites needed to make in order to leave as well as the ten plagues. He particularly elaborated on the plague of the death of the first born. He said that in order to be protected the Israelites had to kill a lamb and smear its blood on the doorposts of their houses. He then stated that blood has various properties which included transport of heat, oxygen and carbon dioxde, homeostatis and protection. The most important being protection. He eloborated and said that the white blood cells in the blood protects us from viral and bacterial invasions and fights on our behalf in order to keep us in our best state. This is analogous to the blood of Christ that was shed to protect us from the disease of sin. This relates to our histology class because last Thursday we discussed blood and its function in the body.
